Though it takes time, documenting your work and achievements is well worth the effort. First of all, well-documented records of your efforts and achievements can be very persuasive when you actually ask for a promotion or are evaluated periodically. This documentation helps everybody, yourself included, to remember exactly what you’ve done and how valuable you are. Seeing them all at once on one document is especially effective.

Also, you’ll appreciate such documentation when you apply for a different job and need to update your resume. Instead of probing murky memories, you’ll have everything you need already written.
